I've had spontaneous "currently unavailable" messages for the past 5 days, and finally got fed up and called tech support, as it was not going away on its own, only getting worse. I then saw that there were thousands of people reading about the same problem on this forum. I tried disconnecting, and reconnecting the coax cable, but it was no help. The Tech support did their thing, reset it, checked it for errors. No errors found. Seems to be working so far after being reset. He suggested the following routine to try on my own if (when) it happens again:
Remote button "Menu"
Settings > System Info
with remote, enter 4883
OK
unplug Set Top Box. I forget how long he said to leave it unplugged, but I've read 30 seconds elsewhere.
He says that with use, the set top box's memory gets cluttered and this process clears and resets it, without loss of recordings. I have the buggy 7216 1, working under release 1.6, build 0689. I've had FIOS since 11/08, and no serious problems until recently. I've only recently begun recording shows and series... I wonder if that's related. A domino effect of the "currently unavailable" issue is that it prevents recordings, when they're affected by the same issue resulting in 6 to 8 sec. recordings.
We'll see how long this fix lasts. The tech said the firmware update was due here in VA end of Jan or into Feb.
